“And as he iourneyed he came neere Damascus, and suddenly there shined round about him a light from heauen.”
1611 King James Version (KJV)
9:3 And suddenly - When God suddenly and vehemently attacks a sinner, it is the highest act of mercy. So Saul, when his rage was come to the height, is taught not to breathe slaughter. And what was wanting in time to confirm him in his discipleship, is compensated by the inexpressible terror he sustained. By his also the suddenly constituted apostle was guarded against the grand snare into which novices are apt to fall.
Ac 9:3 And as he journeyed. It would require six or seven days to make the journey. It was probably made on foot. There shined around about him a light from heaven. Brighter than the sun (Ac 26:13). It was the splendor of the glorified Savior as seen at the Transfiguration (Mt 17:2 Mr 9:3 Lu 9:29), or by John at Patmos (Re 1:16). In order to get the full history of this revelation of Christ and Paul's conversion, we must compare the accounts given by Paul himself in Ac 22:3-21 26:10-20 with Luke's account here.
